Answer:
When directed mutagenesis which is also called reverse genetics is used, only a single mutation per genome is introduced. In contrast, the number of mutations per genome introduced by random mutagenesis is usually difficult to control. It is likely that the strain you obtained with a mutation in gene X after random mutagenesis contained an additional mutation or perhaps multiple mutations which ultimately was/were responsible for loss of virulence in your favorite pathogen.
Answer:
converted into fat and stored in adipose tissue
Explanation:
When protein is taken in excess amount, because it cannot be stored in the body, it can be broken down to amino acids, which is further used as carbon skeletons to synthesize fats, which is then further stored in the adipose tissues.
When the body is not receiving enough calories from other nutrient sources like carbohydrates and fats, the available protein is the used as energy to meet the body's energy demands, by converting it to fat.
Note that, excess intake of protein can be harmful to the body.
Option A and C are correct.
<h3><u>Explanation:</u></h3>
The DNA is the genetic molecule of a cell in an organism that contains the genetic information stored in forms of genes. The genes are expressed by means of protein synthesis. The genes are formed of particular sequence of nitrogen bases that is called as codon. These codons are transcribed into particular amino acids. This process involves the participation of DNA dependent RNA synthase that produces the mRNA from the portion of DNA by means of transcription. The mRNA that is produced from the DNA is formed of complementary nitrogen bases from the DNA, just exception is that in RNA, thymine is replaced by Uracil. This process is known ad transcription.
Answer:
Their skeletal structure and possibly how they look but usually not. You can also look at the way they live and the biomes they live in.
Explanation:
Answer: Option A.
Pure solvent diffused through a membrane but solutes do not.
Explanation:
Osmosis is process where solvents or molecules move from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane which tend to balance the concentration of solutes. Osmosis is passive transport i.e it does not require energy for movement.
